engines and particularly of paper refining engines of theJordan type,which, as is well known, comprise a stationary frusto-conical shellwithin which rotates an endwise adjustable plug, the shell and the plugbeing provided with coacting cutting knives, which, as the plug rotates,comminute or grind up the material in the shell. i Up to a comparativelyrecent period, refining engines of the type stated were always beltdriven. The disadvantages of a belt drive induced a motor driven designwhich, While highly efficient, yet fell short `in some respects ofovercoming the known disadvantages of the belt drive. Experience soondemonstrated the necessity for improving the motor driven design ofengine and various improvements have been proposed to increase itsefficiency. One of the aforesaid improvements proposed theorganizationof the engine in such a manner that the plug shaft and the motor shaftwereconnected to constitute, in effect, a continuous shaft, common tothe plug and the motor, whereby the i motor and the plug might havesimultaneous and coeXtensive endwise movements, when the plug wasadjusted endwise of the shell, to take up the wear of the knives. Thisconstruction still failing to attain that degree of efiiciency which ismandatory, a subsequent improvement was proposed, in which all thefunctions of the construction specifically referred to, were preserved,but independent means were employed toy effect the endwise simultaneousmovements of the p plug and the motor, and such is the state of the artat the present time. The last improvement referred to, viz. that inwhich independent means are employed to effect the endwise simultaneousmovements of the plug and the motor, is much more complicated,cumbersome, and expensive, thanthe construction which it was designed tosupplant, and in addition, provides for some degree of loose play, whichinterferes with the proper relation of the parts during the operation ofadjusting the position of the cone. Therefore, it became apparent to usthat the first construction, e., that in which the shafts of the motorand of the plug are connected to form a common shaft, if improved toeliminateits disadvantages while still retaining its advantages, wouldbe superior in a number of respects to the construction by which it wassupplanted, viz. that which involves the independent means for effectingendwise simultaneous movements of the plug and the motor.

As is well known, the chief difficulty in the driving of Jordan plugs isthe effect of the lateral displacement or sagging of the plug, incidentto its tremendous weight, in causing the binding of the shaft in itsbearings,`and consequently interfering with the operation of themachine, both as to driving and as to adjusting. Ve have discovered thatthe lateral displacement or sagging of the plug can be overcome orrendered practically negligible, by a proper relative positioning of thebearings,` computed with regard to the weight and stresses on the commonshaft of the plug and motor, and we have utilized this fact in the development of a practical machine wherein the motor shaft and the plug shaftare connected to form, in effect, a common shaft for the motor and theplug, in order that said motor y and `plug may have endwise simultaneousmovements consequent to an endwise movement of the shaft and wherein thedisadvantages of the first type of machine involving this organization,are eliminated.

According` to the present invention, the bearings for the common shaftare mounted for endwise movement with said shaft, whereby their properrelation will always be preserved. This organization` differs from theknownV construction in that, in the latter, the bearings are stationaryand the shaft movable axially with relation thereto, as a consequence ofwhich an adjustment of the plug destroyes the proper relation of thebearings. By virtue of our construction referred to, we are enabled touse both a motor drive and a belt drive. This is a fact ofmaterialconsequence, since in certain places or in certain seasons, there are nofacilities for obtaining electric power. The invention also improves theorganization of engines of the type stated by features of constructionwhereby, during the operation of adjusting the plug, the stress incidentto the weight of the motor is taken from the shaft coupling. Theinvention also improves the organization of engines of the type stated,by features of construction which provide for a more ready assemblage.and disassemblage of the parts.

Vithal, the construction proposed is of Simple, durable and inexpensivenature.

A preferred embodiment of the invention is illustrated in theaccompanying draw ings, wherein- Figure 1 is a top plan view of theimproved refining engine, with parts broken away for the sake ofclearness; Fig. 2 1s a side elevation thereof; Fig. 3 is a transversesection on the line 3 3 of Fig. 1; Fig. 4 is a transverse section on theline 4 4 of Fig. l; Fig. 5 is a detail perspective view of a supportingbracket for one of the movable bearings; and Fig. 6 is a detailsectional view showing the relation of the bearing parts and the shafts.

Similar characters of reference designate corresponding parts throughoutthe several vThe shafts 4 and 6, being thus coupled by the device 7,form, in effect, one continuous shaft, common to the plug and to themotor. In environments where electric power cannot be obtained, thedriving of the plug may be effected by a belt transmission, and for thispurpose the shaft 4 may be provided with belt pulleys, as 8. These areof split construction in order that their assemblage and removal may beeffected without interference `with the rest of the organization.

The shaft 4 is journaled in and supported by bearings, as 9 and 10, andthe shaft G is journaled in and supported by bearings, as 11 and 12. Thebearings 9 and 10 are of generally similar construction, the formerbeing associated with the tail box 13 supported adjacent the large endof the shell 1, and the latter being associated with a bracket, as 14,supported adjacent the small ,end of the shell 1. Each of the bearingsaforesaid is of two-part construction, comprising lower members 9a, 10a,11a and 12a, respectively, and upper members 9", 10b,

.11b and 12", respectively. The companion members of each bearing areconnected by bolt fastenmgs, as 15, and are associated with the shaftfor endwise movement therewith. The preferred means of thus associatingthe bearings and the shaft is shown in detail in Fig. 6. In thispreferred construction the bearing members are provided withlongitudinal recesses to receive the shaft and with ribs, as 17, andgrooves, as 18, extending transversely of the shaft. The latter isformed with grooves, as 19, to receive the aforesaid ribs 17 and withribs, as 20, to fit into the aforesaid grooves 18. The ribs 17 and 19thus constitute, in effect, thrust rings to prevent end play of theshaft and to couple the shafts and the bearings in order that the lattermay move axially with the former.

The lower bearing members 9, 10, 11L and 12a are movably associated withtheir respective supports. Means are provided, however, for securing thebearings immovable during the normal operation of the engine, thesecuring means being operable to permit of the movement of the bearingsaforesaid, during the operation of adjusting the position of the plug.

The bearing member 9a is fitted for axial sliding movement in the tailbox 13 and the member 9b is imposed on the member 9, secured thereto bythe bolts 15 as aforesaid and constructed to hold the bearing 9 inproper relation to the tail box and against vertical and lateraldisplacement. Toward this end, the member 9b is provided at its sideswith depending inturned or angle iron flanges, as 21, which fit overfianges, as 22, provided at the sides of the tail box 13. The meansabove referred to for holding the bearing 9 immovable, consists,advantageously, of screws, as 23, which are threaded through the flanges21 and are arranged 105 to have frictional engagement with the flanges22.

The bearing member l0a is fitted for axial sliding movement in thebracket 14 and the member 10b is imposed on the member 10, 11.0 securedthereto by the bolts 15 as aforesaid, and constructed to hold thebearing 10 in proper relation to the bracket 14 and against vertical andlateral displacement. Toward this end, the member 10b is provided at its115 sides with depending inturned or angle iron fianges, as 24, whichfit over flanges, as 25, provided at the sides of the bracket 14. Themeans above referred to for holding the bearing 10 immovable consists,advanta- 120 geously, of screws, as 2G, which are threaded through theflanges 24 and are arranged to have frictional engagement with thefianges 25.

The bearing members 11a and 12a are 125 preferably formed integral witha plate, as 27, upon which the motor 4 is mounted and which is in turnsupported with relation to a carriage plate, as 28. The plates 27 and 28are connected by screw posts, as 29, which 130 provide for suchadjustments of the height i of the motor as may be necessary to insureproper alinement of the parts. The plate 2S is in turn supported withrelation to a base, as 30, and is movable axially thereof. The base 30has at its sides longitudinal channels, as 31, which receive thickenedside portions of the plate 28 and in which are iitted ball bearings, as32, upon which 'the plate 2S rests. At the sides of the base 30,longitudinal bars, as 33, are provided, which overhang the plate 28 andthrough which are threaded screws, as 34, arranged to have frictionalengagement with the plate 28 and employed to hold the latter normallyagainst displacement. The members 9a and 1()EL aforesaid, may beconstructed to run on ball bearings in the same manner as the plate 28'.rlhe member 10a is so shown, the ball bearings 36 upon which said memberrests, being disposed in longitudinal grooves, as 37, in the base of thebracket 14. For the purpose of taking from the coupling 7 such stressesas are incident to the weight of the motor, during the operation ofadjusting the position of the plug, the bearings 10 and 11 may bepositively connected by longitudinally disposed tie bars, as 38.

To facilitate the assemblage and disasseinblage of the engine, the head,as 39, which closes the smaller end of the shell 1 may be of two-partconstruction, as shown in Fig. 5, and the bracket 14, which ispreferably made as one with said head, is also of two-part construction,its sections being j coupled by fastenings which pass through abuttingdepending longitudinal flanges, as 40. By virtue of this construction,the head 39 and bracket 14 may be removed by disuiiiting their parts,and the shaft 4, together withits half of the coupling 7 may be movedthrough the smaller end of the shell 1.

For the purpose of effecting the adj ust-ment of the cone, the usualhand wheel, as 41, is

employed. The threaded staff of this wheel is fitted in the tail box,and its end is connected by a swivel joint, as 42, to the bearing 9.

The manner in which the invention attains the advantages preliminarilyoutlined, will be readily apparent from the foregoing description. Aswas stated, the adjustment of the plug is effected by turning the handwheel 41. This produces an axial movement of the shaft 4 and therewithof the plug.

The bearings 9 and 10 also partake of this axial movement and thus theirrelations, established to provide against sagging or lateraldisplacement of the plug, are accurately preserved. At the saine time,in the case of `a motor drive, the bearings 11 and 12, as

well as the motor, are moved simultaneously and coexteI-isively withtheshaft 4 through the medium of the coupling 7 between said shaft and theshaft 6 and also of the tie bars 38, and thus the relations of thebearings 11 and 12 are accurately preserved. Hence the adjustment oftheplug is not an inducement to its lateral displacement and to theconsequent binding of the shafts in their bearings and interference withthe operations of driving and adjusting. `The construction of thebearings er se is of advantage in that it involves efhcient provisionfor taking up end thrust of the shafts. The provision of the 'tiebars`38 is of advantage in taking stresses from the coupling 7. Byvirtue of the latter, the motor may be put out of service at any timeand a belt drive employed. This is accomplished by removing the boltswhich connect the parts of the coupling. The construction of the bracket14 and the head 39 is of advantage in that it provides for the readyassemblage and disassemblage of the machine. The manner `of mounting themovable parts is of advantage in that it provides for aneasy andfrictionless adjusting operation. In fact, in addition to `the ballbearings aforesaid, to eliminate friction, the parts may be constructedto run in oil and the base construction of the inotoris, in fact, soshown.

The machine as an entirety is self-contained and may be shipped in acompletely organized condition and its construction provides for anabsolutely true relation and alinenient of the parts at all times andunder all conditions;
